I use it as my navigation app. It works better when I got the bigger phone (Not sure how I used it on an iPhone 4s). There is a lot on the screen, but I usually just use the voice navigation feature. It gives pretty good directions most of the time, and reroutes gracefully. Works in many countries. I don't like the UI though. It figures out you've stopped and as I glance to see the map, an add pops up over the top of the screen, which is anoying. Clicking on the bar on the bottom of the screen to "stop" or enter a new address never seems intuitive. Its workable though and good at finding locations by name. One feature it has thats nice, is that you can send someone your route, and it will when your about 2 minutes out (alternatively they can watch your progress).
